I didn’t vote, but personally it seems somewhat obvious to me that the best thing we can do for existing ecosystems, if they have not already been disturbed, is to leave them as they are. Generally the creatures that live there evolved to live there, and the conditions required for the ecosystem to thrive are complex. What I’ve seen of ocean mining involves completely scraping the sea floor of everything and extracting the metals from the disturbed material. Proposed machines leave behind them a complete wake of destruction. There is no possibility to make things better than if we had left it alone. The only opportunity we have to make things better is in areas we have ourselves destroyed. Then we have a chance to improve it. But if something is undisturbed we can’t really improve upon that.
